Automatic fluxing machine

Abstract

An automatic fluxing machine is provided and includes a dispensing section including a surface having through holes formed therein through which flux material is dispensable toward a braze joint and a plugging section disposed below the braze joint to prevent downward flow of dispensed flux material.

The invention claimed is: 
     
       1. An automatic fluxing machine for use with a joint including tubular and frusto-conical parts, the automatic fluxing machine comprising:
 a frusto-conical dispenser having through-holes and an upper edge; 
 a tubular plug, which extends tightly into the tubular part such that an upper portion, a surface of the frusto-conical dispenser and the frusto-conical part define an annulus into which flux material is dispensable through the through-holes and which comprises a first side extending along the surface of the frusto-conical dispenser, a second side extending along the frusto-conical part and a third side extending along the upper portion, 
 the tubular plug comprising a stopper disposed therein to prevent flux material flow through the tubular plug and into the tubular part; and 
 a supplying unit including a conduit, which is coupled to the upper edge of the frusto-conical dispenser, to supply the flux material to the frusto-conical dispenser. 
 
     
     
       2. The automatic fluxing machine according to  claim 1 , wherein a tight fitting between the tubular plug and part prevents flux material flow into the tubular part. 
     
     
       3. The automatic fluxing machine according to  claim 1 , wherein the tubular plug is removable from the tubular part with the flux material dispensed into the annulus. 
     
     
       4. The automatic fluxing machine according to  claim 1 , wherein the frusto-conical dispenser tapers outwardly from the tubular part and terminates at the upper edge. 
     
     
       5. The automatic fluxing machine according to  claim 1 , wherein the tubular plug extends into the tubular part with a uniform diameter and is hollow but for the stopper. 
     
     
       6. A joint forming system, comprising:
 a tubular part; 
 a frusto-conical part extending upwardly from the tubular part; and 
 an automatic fluxing machine configured to form a braze joint along an interior surface of the frusto-conical part, the automatic fluxing machine comprising: 
 a frusto-conical dispenser having through-holes and an upper edge; 
 a tubular plug extendable tightly into the tubular part such that an upper portion, a surface of the frusto-conical dispenser and the frusto-conical part define an annulus into which flux material is dispensable through the through-holes and which comprises a first side extending along the surface of the frusto-conical dispenser, a second side extending along the frusto-conical part and a third side extending along the upper portion, 
 the tubular plug comprising a stopper disposed therein to prevent flux material flow through the tubular plug and into the tubular part; and 
 a supplying unit including a conduit, which is coupled to the upper edge of the frusto-conical dispenser, to supply the flux material to the frusto-conical dispenser.
